MongoDB automated snapshot

WARNING: only use this if your database is small relative to your total storage – the mongodump create full snapshot every time it’s scheduled. See my previous post for MongoDB setup log.

1. Add folder inside of the jail

   [root@homeauto_database]$ mkdir /mnt/backup

2. Create folder on the NAS

   [root@freenas]$ mkdir /mnt/mainsafe/archive/shared/mongodb

3. Link the folders inside of the FreeNAS UI
   
4. Set up backup to BSON files

   [root@homeauto_database]$ vi /root/auto-backup.sh
   #!/bin/sh
   mongodump --db openhab --out /mnt/backup/`date +"%Y%m%d-%H%M"`

   The above scripts creates snapshot of the database openhab (all collections) and timestamps it.
5. Create a cron entry for the job (in my case every day @2:30am)

   [root@homeauto_database]$ crontab -e
   30 2 * * * /root/auto-backup.sh
